“don’t know if this is new but a UK Panasonic sales rep was demoing the GX1 locally –one of only two in the country. Of more interest to me though was a copy of the lens map he showed me. This clearly states 12-35 and 35-100 are both fixed f2.8 with power OIS. If this is final (and surely at this stage it is) then I reckon folk will be fairly pleased about the 35-100 at any rate though some had hoped for a bit faster with the 12-35.”
That the lenses would have constant apertures is not a surprise. And also not that it would have f/2.8. For a lens that was pre announced that it would be “bright” this is really the minimum. But I was hoping for a faster aperture like the amazing Olympus lenses the 14-35mm f/2.0 and the 35-100mm f/2.0. But’ let’s wait. This is not a rumor coming from a very known trusted source.
